The Lowdown

Alright folks, Rusty here. Let’s talk about what’s shaping up for Jaconé. We’ve got a 16-day window, and the first good session isn’t far off.

Tuesday morning (18 August) is a solid start. The swell is a clean 5ft out of the ENE, with a period of 7 seconds. Nothing too long, but it’s packing a moderate punch (combined energy of 372). The wind is a light offshore from the NNE at 6 mph, so the surface will be clean. This is a good, fun size for intermediate surfers, but it might be a little too punchy for total beginners. The crowds can get going here sometimes, so keep that in mind.

The next standout is Friday morning (21 August). Swell bumps up to 6ft from the ENE, with a slightly longer period at 8 seconds. The energy is building nicely (461). The wind is a light offshore again from the NNE (6 mph), leaving it glassy. This is the pick of the first week.

We hit a bit of a lull with some onshore wind and poor conditions over the weekend, but then it gets really interesting.

Sunday afternoon (23 August) shows a solid 6ft swell out of the SSW, but look at the period: 10 seconds. The energy is over 700 (712). That’s a moderate swell with some real kick to it. The wind is a cross-offshore from the ESE at 6 mph, so it’ll be clean. This is a quality wave on the way.

Now, the real meat of the forecast is the Monday 24 August to Wednesday 26 August run. Monday morning has 7ft from the SSW with a 12-second period (energy 1022). That’s a strong groundswell. The wind is a cross-off from the E at 9 mph. This is big, powerful surf. For a beach break, swell this long can get a bit straight, but the energy is undeniable. It’s a big wave day for experienced surfers only – over 8ft, especially on the Tuesday, where it hits 8ft out of the south with a 14-second period (energy 2637). That’s very strong energy. The wind is a cross-off from the ENE at 12-16 mph, but it’s a clean, strong offshore breeze. Wednesday morning (26 August) is still excellent, with 6ft from the south and a 12-second period (energy 1034), with a light cross-off from the NNW. This is another standout session for the experienced crew.

Thursday morning (27 August) is a great catch-up day for the rest of us. The swell drops to a more manageable 5ft from the south, still with a long 12-second period (energy 633). The wind is a glassy offshore from the NE, so conditions will be epic. This is a really good window for intermediate surfers.

After that, the surf fades back down to smaller, cleaner waves through the end of the month and into the first week of September, but nothing that jumps out as a must-surf session. The water temperature here is about what you’d expect for this time of year, so no surprises there.

Overall, the absolute best on offer is the window from Tuesday 26 August morning through Thursday 27 August morning. That’s consistent, long-period groundswell with light to offshore winds. If you’re an experienced surfer, Tuesday the 25th is the biggest, but the 26th is the one that’s both powerful and clean. For the intermediate surfer, Thursday the 27th is the stand-out, forgiving gem.

Rusty.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
